enhance docs to clarify installation #116
Description
the docs mention to install datumaro with pip install datumaro which installs https://pypi.org/project/datumaro/
they should mention to explicitly install with git url of this repository instead.
this will help with compatibility issues especially, since https://pypi.org/project/datumaro/ depends on tritonclient (which depends on cuda-bindings) thus not compatible with macOS.
